Defensive publication

ABSTRACT

COMMINUTED MEAT COMPOSITIONS SUCH AS SAUSAGE CONTAINING UNDENATURED WATER-SOLUBLE LACTALBUMIN. LACTALBUMIN CONCENTRATE IS USED IN THE COMMINUTED MEAT COMPOSITION IN AN AMOUNT IN THE RANGE FROM 1% TO 20%. PROTEIN CONCENTRATION IN THE LACTALBUMIN CONCENTRATE MAY VARY FROM 15 TO 90%. THE LACTALBUMIN CONCENTRATE WHICH IS USED IN ACCORDANCE WITH THIS INVENTION IS PREPARED FROM WHEY BY METHODS WHICH DO NOT INCUR HEAT DENATURATION, AND WHICH DO NOT REQUIRE ADDITION OF CHEMICALS, E.G., LONG CHAIN POLYPHOSPHATES, TO THE WHEY. SUITABLE LACTALBUMIN CONCENTRATES MAY BE PREPARED BY CONCENTRATION OF WHEY BY EVAPORATION AT LOW TEMPERATURES SO AS TO CRYSTALLIZE AND SEPARATE LOCTOSE, BY ELECTRODIALYSIS, WHICH PROVIDES LOWER ASH CONTENT, BY REVERSE OSMOSIS WITH SELECTED MEMBRANES WHICH ALLOWS LACTOSE AND SALT TO GO THROUGH WHILE HOLDING BACK LACTALBUMIN PROTEIN, OR BY INTIAL REFINEMENT OF THE DISPERSED PROTEIN BY PASSING WHEY OR SLIGHTLY CONCENTRATED WHEY THROUGH A SEPHADEX COLUMN OF SELECTED RESINS WHICH HOLDS LACTOSE, AND SALT AND ALLOWS LACTALBUMIN TO GO THROUGH. IN ACCORDANCE WITH THIS INVENTION, CONCENTRATED AQUEOUS LACTALBUMIN, OR SOLID LACTALBUMIN CONCENTRATES CAN BE EMPLOYED. THE INVENTION IS PARTICULARLY APPLICABLE TO THE MANUFACTURE OF WEINERS, FOR EXAMPLE.

Prairie, Wis. 53590 Filed Sept. 25, 1970, Ser. No. 75,707 lint. Cl. A22c US. Cl. 99--108 N0 Drawing. 13 Pages Specification Comminutcd meat compositions such as sausage containing undenatured water-soluble lactalbumin. Lactalbumin concentrate is used in the comminuted meat composition in an amount in the range from 1% to 20%. Protein concentration in the lactalbumin concentrate may vary from 15 to 90%. The lactalbumin concentrate which is used in accordance with this invention is prepared from whey by methods which do not incur heat denature.- tion, and which do not require addition of chemicals, e.g., long chain polyphosphates, to the whey. Suitable lactalbnmin concentrates may be prepared by concentration of whey by evaporation at low temperatures so as to crystallize and separate lactose, by electrodialysis, which provides lower ash content, by reverse osmosis with selected membranes which allows lactose and salt to go through while holding back lactalbumin protein, or by initial refinement of the dispersed protein by passing whey or slightly concentrated whey through a Sephadex column of selected resins which holds lactose and salt and allows lactalbumin to go through. In accordance with this invention, concentrated aqueous lactalbumin, or solid lactalbumin concentrates can be employed. The invention is particularly applicable to the manufacture of wieners, for example.
